Description
Technical field
The present invention relates to be used for the assembling fittings that tubing connects, relate in particular to the tee junction that is used for the tubing connection.
Background technology
Protective screening is a kind of common tubing completed knocked down products; Its frame generally adopts tubing, tee junction and two pass joints to assemble; Three sections adjacent frame places of protective screening connect with tee junction usually, and the tee junction of existing protective screening is to adopt nylon material to make mostly, are easy to generate aging after the tee junction of this material system uses for a long time; Will cause the disengaging of adjacent three sections frames when aging serious; The protective screening that will adopt this tee junction make protective screening lose protective action, if will exist serious potential safety hazard so as the forms protective screening; Simultaneously; The tee junction heat-resisting ability of this material is poor; Burnt roasting just softening easily, fusing, the lawless person who understands this defective can destroy the protective screening that adopts this tee junction very easily, and the anti-theft capability of this protective screening is very poor.For the problem that the tee junction that solves existing nylon material making exists, metal material or the tee junction that other novel anti is aging, exotic material is made have appearred adopting in the market, though this tee junction is difficult aging; And refractoriness is good, but its poor toughness, when being used as the frame connection of protective screening; Frame is prone to loosening; And this material all is a precious materials, has increased the cost of production of tee junction and protective screening, and inconvenience is widely applied in the middle of the protective screening generation.
Publication number is that the Chinese patent document of CN101942959A discloses a kind of protective screening tee junction; Comprise nylon tee junction body; Nylon tee junction body is provided with three sections joints that are used to connect the frame of protective screening, and three sections joints are respectively equipped with an endoporus, and three endoporus are interconnected; Each endoporus all inserts a metal sheet, and three metal sheets are fastenedly connected.This protective screening tee junction, after nylon was partly aging, the frame of protective screening still connected through three metal sheets, avoided the frame of adjacent protective screening to break away from, and had improved the connection reliability of the frame of protective screening greatly; After softening, melting, metal sheet still is not affected to the connection of the frame of protective screening when nylon part quilt baked wheaten cake is roasting, and protective screening can be destroyed easily, has strengthened anti-theft capability; Have and the same toughness of common nylon tee junction, make the connection of frame of protective screening fastening reliable, the phenomenon that can not occur becoming flexible.But its three metal sheets need form through securing member and interconnect, and receive torsion and when producing distortion, will influence the bonding strength of securing member as metal sheet, when this distortion occurs repeatedly, then might cause the connection of securing member to lose efficacy; When mounted, three metal sheets must connect through the securing member more than two, can prevent that so just metal sheet from producing relative rotation, and guarantee bonding strength, but this makes fitting operation complicated, has increased human cost, has reduced packaging efficiency; In addition, this kind tee junction outside the connecting portion of tee junction is exposed to, can't form unification with after the frame of protective screening is connected with metal edge frame.
Summary of the invention
The technical problem that the present invention will solve is the deficiency that overcomes prior art, provide a kind of connect reliable, safety factor is high, simple in structure, be convenient to make, with low cost be used for the tee junction that tubing connects.
For solving the problems of the technologies described above, the present invention adopts following technical scheme:

Said monolithic metal sheet is made up of two vertical each other alar parts that join.
The all L-shaped tabular of said two alar parts, two L shaped flat alar parts intersect with a long limit, and prolong intersection and be symmetrical set.
Said slot and the profiling of monolithic metal sheet are provided with.
Said metal valve jacket comprises exterior angle cover and interior angle cover, and said exterior angle cover and interior angle overlap respectively and the connecting portion clamping.
Said exterior angle cover is made up of three orthogonal panels, one of them panel be provided with can with the trip of adjacent two tubing clampings,
Said connecting portion is provided with the trip storage tank, and said trip places the trip storage tank.
Be respectively equipped with first dovetail on two other panel of said exterior angle cover; First dovetail on said two panels is arranged in parallel; Be equipped with first dovetail groove on two lateral surfaces of said connecting portion, first dovetail is inserted in the first corresponding dovetail groove.
Said interior angle cover is made up of three orthogonal baffle plates; The cross section of said three baffle plates is L shaped; One of them baffle plate is provided with second dovetail along its bearing of trend, and said connecting portion is provided with the second corresponding dovetail groove, and said second dovetail is inserted in second dovetail groove.
Two other baffle plate of said interior angle cover is provided with the rib that can be compressed by a tubing.
Three panels of said exterior angle cover are corresponding one by one with three baffle plates of said interior angle cover, and each panel mask is in the end of corresponding baffle plate.
Compared with prior art, the invention has the advantages that:
The tee junction that is used for the tubing connection of the present invention; On nylon tee junction body, offer the slot that extends to three sections joints from connecting portion, be inserted with the monolithic metal sheet that extends to three sections joints from connecting portion in the slot, when this valve jacket formula tee junction is used for the connection of protective screening tubing; Can tubing, nylon tee junction body and monolithic metal sheet three be connected as a single entity through securing member; Make its all advantages that possess existing nylon structure of steel pole tee junction, in installation process, need not simplify installation steps greatly through the metal sheet of securing member connection separated body formula; Saved the manpower and materials cost; And, to have eliminated split type metal sheet fully and might occur connecting the potential safety hazard that inefficacy brings, safety further improves; Simultaneously; The connecting portion of nylon tee junction body is coated with the metal valve jacket; This metal valve jacket not only can hide slot and monolithic metal sheet, makes that the protective screening after the assembling has good whole property, and makes the whole protection netting gear be equipped with unified metal-like; And be convenient to the metal valve jacket paintedly, make it to form optimal collocation of colour with the frame of protective screening.The monolithic metal sheet is made up of two vertical each other alar parts that join, and this metal plate structure is simple, and it is convenient to peg graft; Be convenient to install; The slot of profiling setting also possesses same simple structure with it simultaneously, is convenient to nylon tee junction body is carried out the mould design, reduces die cost.The metal valve jacket comprises exterior angle cover and interior angle cover, and exterior angle cover and interior angle overlap respectively and connecting portion clamping, convenience quick for installation.Three panels of exterior angle cover are corresponding one by one with three baffle plates of interior angle cover, and each panel mask makes the tee junction profile neat, attractive in appearance in the end of corresponding baffle plate.
